J. B. BUCKLEY BOILER Filed March' 10, 1926 i ms i Thedpresentinvention relates to improveeleaningi automobile chassis and the prinboiler in such; manner as to continuously snbjectthe same to the heat radiations' fr'om aso'urce otheat supply disposedfat the base jo'f fine boiler andi jsuccessively recirculating 10' thepreheatedWater"through the boiler for 'c I subjectiontolthe heating radiations; Y I V "Another' i objectjof the invention -conte mplatesftheipronision of expansive connections ighetween the heating coiland supporting col- LuInnandthe heating coil and drum to allow aentirety from' the boiler.

Wh'at' I claim is 1.-. Afboiler. casing, a heating coil therein, a

"chamber iwith which the upper endof said lower end ofsaid column, the arms of said fitting being directed toward diametrically leading to one ofrsaid arms through the boiler wall atthat-side, affeed pipe for saidcoil "having a detachable section connected with within the last'me'ntioned T-fitting arm to dedrum connection, wherein the collar 63 may be the spirit and scope of" I i i pipe have been removedtherefrom.

centrali-tub'ular column, there being a steam c olumnf-and coil communicate, an inverted T-- 'fittingfthestem of which-is secured to the 'positegsidesflof the boiler, a supply pipe thelopposite arm of 'said' T-fitting, means I tLLEt-achablyfastenls'aidfeed pipe-therein, said externally threaded plug in said'last named arm, said supply pipe being screwed into said'plug and being adapted for unscrewing wall to permit the removal of said means and subsequent releasing of said coil feed pipe I therefrom and withdrawal through -the'boiler arm of said T-fitting which receives said plug.

'2. The combination, with a boiler casing having therein a steam drum; of a T-fitting, a

columnone end of which communicates with said drum and the'other with the stem of said fitting around said joint, a supply pipe, a renicates therewith and a retaining nut on the end of said feed pipe for the coi1,'sa id nut being accessible for unscrewing by a; suitable toolinserted through-the opposite arm of the T-fitting after said plug and supply 3. The combination with agb'oiler having a steam drum; of a T-fitting, a columncommunicating between said drum and the stemof said T-fitting, a heating coil, a feedpipe therefor communicating with one arm of said T-fittingby means of a slip joint, and a packing'gland arranged interiorly of said T -fitting aifording a water tight connection aroundrsaid joint, said packing gland being accessible through'the other arm of'said T- fitting, l I l In testimony whereof I have afiixed my signature.
